Team sources tell ESPN that Goff, 22, will start at quarterback when the Rams take on the Miami Dolphins on Sunday. Quarterback Case Keenum, who has started all of Los Angeles’ games this season, will be his backup.

Goff and Keenum were informed of the lineup change on Tuesday after meeting with Rams coach Jeff Fisher, according to the sources.
